Abstract

A toothbrush includes a handle, a head at a distal end of the handle comprising a bristle plate, a hole extending through the bristle plate, a plurality of bristles at least partially disposed in the hole and extending from the hole in a direction away from the head, and a reservoir in fluid communication with the hole. Fluid in the reservoir enters the tuft holes and is wicked out of the head of the toothbrushes by capillaries formed between the bristles.
